- This document is a quick reference guide of a list of all
- the available functions using Gemdos, BIOS and XBIOS. An explanation
- of the columns follows:
-
- Number - opcode number for the function in hex
- Name - name of the function
- Add - amount added to stack after execution of function
- Comment - brief description of function
-
- e.g. ...... ...,-(sp)
- ...... ...,-(sp)
- move.w #number,-(sp)
- trap #1
- add.l #add,sp
